In order to laterally adjust the tractionwheel or the wheel proper, it is but necessary to loosen the nuts on the shaft, it being understood that turning the nuts in one direction will lengthen the distance of the wheels one "from the other and turning the nuts in an opposite direction will shorten the distance mg or space.

2. In combination with an axle, supporting-Wheels thereon, a traction-Wheel inclosing said supporting-Wheels, each of the traction-wheels having annular flan es on their opposite faces and caps carried y the axle and engaging the flanges of-the traetion- Wheel, said traction lvheel being free to re" volve Within the caps of the axles. 3.
